Letters Patent No. 91,084, dated June 8, 1869.

IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of thesame.

To allavhom it may conce/rn 'Be it known that I, DAVID F. GARR, of' EastUnion township, in the county of Wayne, and State of Ohio, have inventedcertain new and useful Improvements in Cultivators; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, forming partof this spectication, in which@ Figure 1 is a side elevation, and

Figure 2 is a plan.

These improvements relate to a two-wheeled cultivater, having a numberof beams provided with shovels, connected with the axle of the mainwheels by loops and nuts, and braced, as hereafter to beshown; alsohaving a linked lever,by operating which the cultivator-sbovels areraised simultaneously from the soil.

A are the wheels, and

B, the axle, square in form.

C are the shovel-beams, the upper ends of which rest against the underside of the axle, andare rigidly connected with the latter by means ofthe'loops E, which pass around the axle, thence through holes in thebeams, and are secured, by nuts on their screw-ends, on the lower sidesof the beams, as clearly seen in the drawings.

'The beams C, extending back from the axle, are curved to a slight`forward incline, and have suitable shovels F, attached by bolts orotherwise to their lower ends.

The beams are of dierent alternate lengths, so that the plows of thelonger beams are back a short distance from the line of the shovels onthe shorter beams.

G are the braces to strengthen the beams C, to which they are attachedby their rear ends passing through holes therein, and anut screwed on.Extending diagonally upward, the braces are looped to the forward endsof the loops E, the nut being/placed thereon after the brace-end.

H is a rectangular or other suitably-formed frame,

hinged to the axle B by the hinges!) b, and provided with a driveiisseat, I, and tongue, 1x

L is a standard inserted in the forward part of the Ml is a link,pivoted at one end to the lever M, and at the other end to the bent armM2, which is bolted to the upper side of the axle B, and thence curvedback and up, as shown in lig. 1, so that when the lever M is lifted, theaxle will turn within the wheels, thus raising the shovels F as far asdesired from the soil.

In order to regulate the raising of the shovels, the level' is furnishedwith. several holes for the bolt which connects it with the link M, sothat the height to which the shovels are raised is governed by thepositionl of the holt.

The lever, it will be seen, when upright is self-locking, hence the useof the adjustable link M.

In g. 2, of the drawings, a cultivator as herein described is shown,provided with seven beams and shovels. It may be drawn by two horses; byturning the cultivator at the end of the cultivated rows, the sameground may be twice gone over.

This cultivator may be adjusted froma field-cultivator to a cotton,corn, or potato-cultivator, by removing the centre-beam from the axle,and, if desirable, by substituting regular shovel-plows for the shovelsof the remaining middle two beams; and shovel-plows may also be usedinstead of the cultivator-plows shown, whenever necessary, the manner inwhich the shovels are connected with the beams rendering their removaleasy; by removing all but two beams from the axle, and placing these twoat a suitable distance apart, the machine may be used in marking orspacing corn or cotton-lands.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with the axle B of the beams C, loops E, braces G,and shovels F, when adjusted and arranged substantially as and for thepurpose speciied. i

2. The lever Maud link M,n combination with the axle B and parts aboveclaimed, as and. for the purpose set forth.
